I’m which sentence is a comma used correctly

To determine which sentence uses a comma correctly, let's review the main rules for comma usage:

1. Independent clauses: A comma is used before a coordinating conjunction (such as "and," "but," "or," etc.) when joining two independent clauses.

Example: I went to the store, and I bought some groceries.

2. Introductory phrases: A comma is used after introductory words or phrases at the beginning of a sentence.

Example: However, I didn't have enough money to buy everything I wanted.

3. Appositives: A comma is used to set off non-essential information or explanations within a sentence.

Example: John, my brother, is an excellent tennis player.

Now, without the sentences to choose from, I can't tell you the specific sentence, but I'll provide two examples using correct comma usage:

Example 1: I enjoy cooking, and I also like baking.
- This sentence uses a comma correctly before the coordinating conjunction "and" to join two independent clauses.

Example 2: In the morning, I like to drink coffee.
- This sentence uses a comma correctly after the introductory phrase "In the morning."

To identify a sentence with correct comma usage, look for instances where commas are used to separate independent clauses, introductory phrases, or appositives. Remember that sentence structure can vary.
